Autism and neurodevelopmental disability risks in children with tracheostomies and ventilators.

BACKGROUND/OBJECTIVE: Infants who survive prematurity and other critical illnesses and require continued invasive mechanical ventilation (IMV) postdischarge (at home) are at high risk of developmental delays and disabilities. Studies of extremely preterm cohorts (<28-week gestation) demonstrate rates of 25% for intellectual disability (ID) and 7% for autism spectrum disorder (ASD). Rates of ASD and ID in children with IMV are unknown. This study aimed to determine neurodevelopmental disability risk in a cohort of children with postdischarge IMV. DESIGN/METHODS: A consecutive series of children with IMV were assessed 1 month, 6 months, and 1 year after discharge. Cognitive, social, and communicative domains were assessed by a Developmental and Behavioral Pediatrician using (1) clinical adaptive test/clinical linguistic and auditory milestone scale (CAT/CLAMS) of the capute scales; (2) pediatric evaluation of disability inventory computer adaptive test (PEDI-CAT); and (3) modified checklist for autism in toddlers, revised (MCHAT-R). Red flag signs and symptoms of ASD using DSM-V criteria were noted. Longitudinal testing was reviewed. Expert consensus impressions of evolving ASD and/or ID were determined. RESULTS: Eighteen children were followed for 1 year; at 1 year, the median age (range) was 23 (17-42) months. Children were 44% male, 33% non-Hispanic White, 39% non-Hispanic Black, and 28% Hispanic. Fifteen (83%) children were prematurity survivors. Median (range) developmental quotients (DQs): full-scale DQ 59 (11-86), CAT DQ 66.5 (8-96), and CLAMS DQ 49.5 (13-100). Twelve (67%) children were highly suspicious for ASD and/or evolving ID. CONCLUSIONS/SIGNIFICANCE: This cohort of children with at-home IMV demonstrates a higher risk of ASD and ID than prior premature cohorts. Larger investigations with longer follow-up are needed.

Home Health Nursing Agencies' Services for Children With Medical Complexity: Parent and Nurse Perspectives.

OBJECTIVE: Many children with medical complexity (CMC) require the services of home health nurses (HHNs). Home health agencies (HHAs) hire, train, and manage nurses. For children to flourish, families, nurses, and HHAs must establish successful working relationships. Our objective was to understand the perspectives of parents and nurses about HHAs. METHODS: In Illinois (IL) from 2019 to 2022, HHNs for and parents of children with invasive mechanical ventilation were interviewed. In North Carolina (NC) from 2012 to 2013, parents of CMC were interviewed, and from 2013 to 2014 HHNs participated in focus groups. Each dataset was initially analyzed separately for main themes relating to HHAs. Using collaborative thematic analysis, we determined themes common across datasets. RESULTS: In IL, 23 mothers, 12 fathers, and 20 nurses were interviewed. In NC, 19 mothers, 6 fathers, and 1 grandmother were interviewed; and 4 focus groups of 18 nurses were conducted. Four common themes were identified. 1) HHAs do not have a uniform process for hiring and assigning nurses to cases. 2) HHAs have marked variability in training offered to nurses. 3) Shift scheduling, notifications, and communications with the HHAs frustrate parents and nurses. 4) Nurses and parents have little allegiance to specific HHAs; they frequently change agencies or work with several simultaneously. CONCLUSIONS: Parents and nurses perceive practices for hiring, training, and staffing as inconsistent, and experience communication challenges. HHA-level problems may contribute to issues with HHN retention and complicate the lives of the families of CMC. Further research about this critical health care sector is needed.

BEhavioral Health Stratified Treatment (B.E.S.T.) to optimize transition to adulthood for youth with intellectual and/or developmental disabilities.

Youth with intellectual and/or developmental disabilities (IDD) often struggle with depression and anxiety, which adversely impacts transition to adulthood. Integrated behavioral health care coordination, wherein care coordinators and behavioral health specialists collaborate to provide systematic, cost-effective, patient-centered care, is a promising strategy to improve access to behavioral health services and address factors that impact transition to adulthood, including depression/anxiety symptoms. Current care coordination models (e.g., Title V Maternal and Child Health Bureau [MCHB]) do not include behavioral health services. The CHECK (Coordinated HealthCarE for Complex Kids) mental health model, hereby refined and renamed BEhavioral Health Stratified Treatment (B.E.S.T.), is a behavioral health intervention delivery program designed for integration into care coordination programs. This study aims to determine whether an integrated behavioral health care coordination strategy (i.e., MCHB care coordination plus B.E.S.T.) would be more acceptable and lead to better youth health and transition outcomes, relative to standard care coordination (i.e., MCHB care coordination alone). Results would guide future investment in improving outcomes for youth with IDD. This study is a two-arm randomized clinical trial of 780 transition-aged youth with IDD (13-20 years) to evaluate the comparable efficacy of MCHB Care Coordination alone vs. MCHB Care Coordination plus B.E.S.T. on the following outcomes: 1) decreased symptoms and episodes of depression and anxiety over time; 2) improved health behaviors, adaptive functioning and health related quality of life; 3) increased health care transition (HCT) readiness; and 4) improved engagement and satisfaction with care coordination among stakeholders.

Home health nurses for children with invasive mechanical ventilation (IMV): Perspectives on gaps and opportunities for recruitment.

BACKGROUND: Children with medical complexity (CMC) dependent on invasive mechanical ventilation (IMV) often require private duty home nursing; however, there are ubiquitous shortages. Home health is an especially vulnerable nursing sector because of less competitive wages and less prominence during nursing education. We sought to understand nurses' perspectives on gaps and opportunities for recruiting home care nurses for children with IMV. METHODS: Home health nurses experienced with children with IMV were recruited for semi-structured interviews. The interview guide served as the initial codebook which was iteratively modified as themes emerged. This study presents an analysis of quotes related to field entry and home health experiences. FINDINGS: Twenty interviews were completed with primarily female (95%) participants. The majority worked full-time (60%) and had an average of 11 years of experience. During nursing education, participants described a lack of exposure to private duty home health nursing. Many entered the field serendipitously, because of a passion for care of CMC or to continue care for a hospitalized patient. Challenges to employment included lack of competitive wages and benefits. Nurses remained in the field because of the rewarding work with patients and families, schedule flexibility, slower pace, and one-on-one care. DISCUSSION: Home health nurses for IMV describe lack of employment benefits. However, the opportunity to work longitudinally and individually with patients was rewarding. APPLICATION TO PRACTICE: Creative solutions must be explored to recruit and sustain this essential workforce, including exposure during nursing education, improved training and benefits, and targeted recruiting.

Diagnosis of autism in a rare case of tyrosine hydroxylase deficiency: a case report.

BACKGROUND: Tyrosine hydroxylase deficiency (THD) is a rare movement disorder with broad phenotypic expression caused by bi-allelic mutations in the TH gene, which encode for tyrosine hydroxylase (TH) protein. Some patients with THD have improvement in dystonia with carbidopa-levodopa, a synthetic form of dopamine typically used in Parkinson's disease, and are considered to have dopa-responsive THD. THD has been found in 0.5-1 per million persons, although due to overlapping symptoms with other disorders and the need for genetic testing, prevalence is likely underestimated. Existing literature describes some patients with THD having intellectual disability, but comorbid autism spectrum disorder (ASD) has not been reported. CASE PRESENTATION: A nearly 3-year-old boy was referred to pediatric neurology due to hypotonia, delayed motor milestones, and expressive speech delay. Whole exome sequencing confirmed tyrosine hydroxylase deficiency, detecting a novel variant p.S307C first reported here. The child was treated with carbidopa-levodopa with an excellent response, resulting in improved balance, fewer falls, and improved ability to jump, run and climb stairs. He was determined to have dopa-responsive THD. Due to his delays in expressive speech, the boy also had an assessment with a developmental and behavioral pediatrician, who identified a pattern of social pragmatic speech delay, sensory sensitivities, and restricted interests, and determined that he met criteria for a diagnosis of ASD. CONCLUSIONS: While ASD can stand alone as a clinical diagnosis, it is also a cardinal feature of other genetically-based neurological disorders. To our knowledge, this is the first case that describes a patient with both disorders. Perhaps THD may be among the genetic disorders linked with ASD.

Early childhood developmental skills of children with tracheostomies and ventilators recently discharged home.

BACKGROUND: Infants who survive prematurity and critical illnesses but require ongoing invasive mechanical ventilation (IMV) are at high risk for developmental disabilities. However, their detailed developmental profiles are largely unknown. OBJECTIVE: To understand the developmental profiles of a cohort of young children with IMV after hospital-to-home transition. DESIGN/METHODS: Developmental testing was completed 1 month after hospital discharge to determine functioning within motor, cognitive, and communicative domains using (1) the Clinical Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS); (2) the Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT); and (3) The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA-FS). To complement validated testing, semi-structured interviews were conducted with parents to understand perceived influences on neurodevelopment. RESULTS: Twenty children were evaluated at median (range) age 11 (5-27) months. Nearly half (45%) were male, 40% non-Hispanic Black, and 25% Hispanic. Sixteen (80%) children were survivors of prematurity. After gestational age correction, median (range) full-scale developmental quotients (DQ) were 69.5 (8-119): CAT DQ 62.5 (3-113) and CLAMS DQ 71.5 (12-125). Parents described that prolonged restriction within the hospital crib away from caregivers, despite hospital therapists, impedes development. Home environments improve development primarily through increased time with parents, but also play outside of the crib. One month after hospital discharge only 10% were receiving early intervention therapies. CONCLUSIONS/SIGNIFICANCE: Children with IMV display wide ranges of neurodevelopmental skills with a majority experiencing substantial delays in motor, communicative, and adaptive functioning. The degree and cross-domain challenges highlight the need for targeted and timely therapeutic strategies.

PICU Survivorship: Factors Affecting Feasibility and Cohort Retention in a Long-Term Outcomes Study.

Our understanding of longitudinal outcomes of Pediatric Intensive Care Unit (PICU) survivors is limited by the heterogeneity of follow-up intervals, populations, and outcomes assessed. We sought to demonstrate (1) the feasibility of longitudinal multidimensional outcome assessment and (2) methods to promote cohort retention. The objective of this presented study was to provide details of follow-up methodology in a PICU survivor cohort and not to present the outcomes at long-term follow-up for this cohort. We enrolled 152 children aged 0 to 17 years admitted to the PICU in a prospective longitudinal cohort study. We examined resource utilization, family impact of critical illness, and neurodevelopment using the PICU Outcomes Portfolio (POP) Survey which included a study-specific survey and validated tools: 1. Functional Status Scale, 2. Pediatric Evaluation of Disability Inventory Computer Adaptive Test, 3. Pediatric Quality of Life Inventory, 4. Strengths and Difficulties Questionnaire, and 5. Vanderbilt Assessment Scales for Attention Deficit-Hyperactivity Disorder. POP Survey completion rates were 89%, 78%, and 84% at 1, 3, and 6 months. Follow-up rates at 1, 2, and 3 years were 80%, 55%, and 43%. Implementing a longitudinal multidimensional outcome portfolio for PICU survivors is feasible within an urban, tertiary-care, academic hospital. Our attrition after one year demonstrates the long-term follow-up challenges in this population. Our findings inform ongoing efforts to implement core outcome sets after pediatric critical illness.

The Role of Care Coordinators for Children with Respiratory Technologies and Home Nursing.

Background: Children with respiratory technologies, particularly those with mechanical ventilation, represent a growing population that require complex home nursing, medical equipment, outpatient medical and habilitative supports to live and thrive in their community. Care coordination is essential to support these children and their families to navigate and integrate key community-based health and educational services, however, care is often fragmented and care coordination needs unmet. Therefore, to fully support children with respiratory technologies, it is critical to understand the role of care coordinators (CCs) and how to sustain this workforce. The aim of this article is to describe CCs' perspective on (1) their role in supporting families in a home care program for children with respiratory technologies and home nursing, and (2) the core components of recruiting into and sustaining the CC workforce. Methods: Semistructured interviews were conducted with 15 CC from the Division of Specialized Care for Children (DSCC) Home Care program for children with technology dependence and home nursing in Illinois. Two independent coders utilized a modified template approach and discussed to agreement to analyze transcripts. Results: CC averaged 6.6 years of CC experience; the majority had social work or nursing backgrounds. CCs' job satisfaction was derived from their role supporting hospital discharge, seeing children improve over time, and navigating challenges with families. CCs enjoyed working in a collaborative environment where they could draw from their colleagues' experience to solve problems. Job dissatisfaction and job turnover stemmed from difficult family interactions, high caseloads, and redundant and time-intensive administrative tasks, which interfered with family engagement. Conclusions: CCs for children with respiratory technologies require diverse skills, but interdisciplinary teams enable collaborative support of families. Seeing children thrive can sustain the workforce, however, CCs report challenges due to high caseloads and administrative tasks, which impede direct family involvement.

Scaffolding Parenting and Health Development for Preterm Flourishing Across the Life Course.

Advances in obstetrics and neonatal medicine have resulted in improved survival rates for preterm infants. Remarkably, >75% extremely (<28 weeks) preterm infants who leave the NICU do not experience major neurodevelopmental disabilities, although >50% experience more minor challenges in communication, perception, cognition, attention, regulatory, and executive function that can adversely impact educational and social function resulting in physical, behavioral, and social health issues in adulthood. Even late premature (32-36 weeks) infants have more neurodevelopmental challenges than term infants. Although early intervention and educational programs can mitigate risks of prematurity for children's developmental trajectories, restrictive eligibility requirement and limitations on frequency and intensity mean that many premature infants must "fail first" to trigger services. Social challenges, including lack of family resources, unsafe neighborhoods, structural racism, and parental substance use, may compound biological vulnerabilities, yet existing services are ill-equipped to respond. An intervention system for premature infants designed according to Life Course Health Development principles would instead focus on health optimization from the start; support emerging developmental capabilities such as self-regulation and formation of reciprocal secure early relationships; be tailored to each child's unique neurodevelopmental profile and social circumstances; and be vertically, horizontally, and longitudinally integrated across levels (individual, family, community), domains (health, education), and time. Recognizing the increased demands placed on parents, it would include parental mental health supports and provision of trauma-informed care. This developmental scaffolding would incorporate parenting, health, and developmental interventions, with the aim of improved health trajectories across the whole of the life course.

Desymmetrization of Diols by Phosphorylation with a Titanium-BINOLate Catalyst.

The desymmetrization of ten prochiral diols by phosphoryl transfer with a titanium-BINOLate complex is discussed. The phosphorylation of nine 1,3-propane diols is achieved in yields of 50-98%. Enantiomeric ratios as high as 92:8 are achieved with diols containing a quaternary C-2 center incorporating a protected amine. The chiral ligand, base, solvent, and stoichiometry are evaluated along with a nonlinear effect study to support an active catalyst species that is oligomeric in chiral ligand. The use of pyrophosphates as the phosphorylating agent in the desymmetrization facilitates a user-friendly method for enantioselective phosphorylation with desirable protecting groups (benzyl, o-nitrobenzyl) on the phosphate product.

Recruitment of patients with chronic kidney disease and obstructive sleep apnoea for a clinical trial.

Obstructive sleep apnoea is common in chronic kidney disease (CKD) and may accelerate the decline in kidney function. Recruitment for a randomised controlled trial to address whether treatment of sleep apnoea with continuous positive airway pressure (CPAP) slows the progression of kidney failure may be challenging because sleep apnoea is often asymptomatic in this patient population. The present report outlines recruitment challenges and how to address them. Adult patients with CKD were recruited for a 12-month randomised, controlled, non-blinded, parallel clinical trial to evaluate the impact of CPAP therapy on kidney function. Patients completed a home sleep apnoea test and those that met pre-specified sleep apnoea and nocturnal hypoxaemia severity criteria were randomised to receive CPAP or no therapy. Although 1,665 patients were eligible to participate in the study over 3 years, only 57 (3.4%) were ultimately randomised. The sequential reasons (and number of patients) for recruitment failure were: no show at clinic appointment (137), insufficient recruiters to approach every eligible patient (461), on therapy for sleep apnoea (122), unable to provide informed consent (67), refused consent (645), home sleep apnoea test not completed (47) or inclusion criteria not met (116), and declined pre-randomisation education session (12). Many challenges limit effective recruitment, which may be addressed by hiring additional recruiters and increasing the awareness of sleep apnoea among patients with CKD. These findings can be used to improve recruitment strategies and the design of future studies.

Effect of CPAP Therapy on Kidney Function in Patients With Chronic Kidney Disease: A Pilot Randomized Controlled Trial.

BACKGROUND: OSA is common in chronic kidney disease (CKD) and may accelerate a decline in kidney function. It is not clear whether treatment of OSA with CPAP improves kidney function. RESEARCH QUESTION: Does treatment with CPAP improve kidney function in patients with CKD and coexisting OSA? STUDY DESIGN AND METHODS: A randomized, controlled, nonblinded, parallel clinical trial was performed of patients with stages 3 and 4 CKD and coexisting OSA comparing the effect of CPAP vs usual care on the estimated glomerular filtration rate (eGFR) and the urine albumin to creatinine ratio (ACR) over 12 months. RESULTS: Fifty-seven patients were enrolled and 30 were randomized to CPAP. They had moderately severe CKD (eGFR, 38.4 ± 1.5 mL/min/1.73 m2) and significant OSA and nocturnal hypoxemia (oxygen desaturation index: 23.9 events/h; interquartile range [IQR], 20.3 events/h; mean peripheral capillary oxygen saturation: 89.5%; IQR, 1.7%); 60% had baseline albuminuria (ACR, > 3 mg/mmol). No significant difference was found between CPAP and usual care in the change in eGFR and ACR over 12 months. Although some improvement in eGFR occurred with CPAP therapy in patients with a lower risk of CKD progression, this did not reach statistical significance. INTERPRETATION: Although CPAP did not provide additional renal benefits over usual care in all CKD patients, some evidence suggested that CPAP slowed the decline in eGFR in CKD patients with a lower risk of CKD progression. These preliminary data support the need for larger clinical trials exploring the effects of CPAP on kidney function.

Intake, nutrient digestibility, rumen parameters, growth rate, carcase characteristics and cannabinoid residues of sheep fed pelleted rations containing hemp (Cannabis sativa L.) stubble.

The feeding value and impact of hemp stubble in the diet of ruminants is unknown. Fifteen Merino castrated male sheep were maintained in individual pens and fed one of three pelletized experimental inclusion diets, as a 0% (Control), 28% (Hemp 1), and 56% (Hemp 2) pellet that delivered a diet meeting the nutrient requirements of the animals. Inclusion of hemp stubble had no effect (P > 0.05) on either DM intake, live weight gain or the feed to gain ratio but positively impacted (P < 0.05) on nutrient digestibility. Hemp stubble inclusion increased the concentration (but not molar proportions) of acetic and butyric acids and increased both the concentrations and molar proportions of iso-butyric, iso-valeric, hexanoic and heptanoic acids, possibly due to increased protein digestibility and/or changes in the composition of rumen cellulolytic bacteria. Tetrahydrocannabinolic acid (THCA) was the only cannabinoid found in plasma in the sheep fed the hemp-containing diets, and this was found at very low concentrations (<16 µg/L). The psychoactive cannabinoid delta-9-tetrahydrocannabinol (Δ 9-THC) was not detected in any plasma samples. THCA was detected in the liver of two sheep fed the Hemp 1 pellets and two sheep fed the Hemp 2 pellets. Cannabidiol (CBD) was detected in the liver of one sheep fed the Hemp 2 pellets (but no liver THCA was detected in this sheep). Δ 9-THC was detected in both the kidney fat and subcutaneous fat of all sheep fed hemp stubble, with the concentrations being higher (P < 0.05) in the sheep fed the Hemp 1 pellets. THCA was also detected in the subcutaneous fat of one of the sheep fed the Hemp 1 pellets. Four of the five sheep fed the Hemp 1 pellet and one of the five sheep fed Hemp 2 pellet had detectable levels of Δ 9-THC in the meat (loin). No other cannabinoids were detected in the meat. Current food standards regulations in Australia prohibit presence of any cannabinoid residues in commercial meat products; thus, determination of a withholding period is required to enable the safe feeding of hemp-stubble to sheep. Further research is also required to gain a greater understanding of the rumen metabolism of cannabinoids.

Cognitive Function in a Sleep Clinic Cohort of Patients with Obstructive Sleep Apnea.

Rationale: Obstructive sleep apnea (OSA) is associated with an increased risk of mild cognitive impairment (MCI) within the general population. However, MCI risk in sleep-clinic populations of patients with OSA is poorly characterized.Objectives: To determine the prevalence of MCI in a sleep-clinic population of patients with OSA and which patients are at the greatest risk for this complication.Methods: Adults (n = 1,084) referred to three academic sleep centers for suspected OSA who had home sleep apnea testing or in-laboratory polysomnography were recruited. Patients completed sleep and medical history questionnaires, the Montreal Cognitive Assessment Test (MoCA) of global cognition, the Rey Auditory Verbal Learning Test of memory, and the Wechsler Adult Intelligence Scale-Fourth Edition Digit-Symbol Coding (DSC) subtest of information processing speed.Results: A MoCA score <26 (range 0-30) was operationally defined as MCI. MCI was present in 47.9% of our entire patient cohort, increasing to >55.3% in patients with moderate and severe OSA. Patients with a MoCA <26 were predominantly older males with more severe OSA, hypoxemia, and vascular comorbidities. Moderate and severe OSA were independently associated with >70% higher odds for MCI compared with patients with no OSA (P = 0.003). Memory and information processing speed was lower than age-matched normal values (P < 0.001), with lower MoCA and DSC scores associated with a higher oxygen desaturation index and nocturnal hypoxemia.Conclusions: Cognitive impairment is highly prevalent in patients referred to sleep clinics for suspected OSA, occurring predominantly in older males with moderate to severe OSA and concurrent vascular comorbidities. Moderate to severe OSA is an independent risk factor for MCI.

Late adolescent & young adult functioning and participation outcomes after prematurity.

There has been an increased emphasis on optimizing health, developmental, and behavioral outcomes over the life course after prematurity. An important framework for examining adolescent and young adult outcomes is the International Classification of Functioning Disability and Health Children (ICF) developed by the World Health Organization (WHO) in 2001 and expanded to children and youth (ICF-CY) under age 19 years in 2007. The ICF and the ICF-CY can be used as a statistical tool in population studies, a research tool to measure outcomes, quality of life, and environmental factors, a clinical tool for outcomes of rehabilitation and vocation training, and as a social policy-educational tool to raise awareness and promote social action for equity. In this review we describe how functioning and participation can help inform transitional outcomes at age 17 years and emerging adult independence at 23 years. We highlight outcomes in adolescence and adulthood of former preterm infants using the ICF domains of functioning and participation. We include current standardized adaptive assessments (Vineland Adaptive Behavior Scales-3rd Edition; VABS3) and Adaptive Behavior Assessment Scale-3; ABAS3) that measure self-care daily living skills, applied learning, and social functioning. We also emphasize that participation involves life activities of higher education attainment, completing vocational training, experiencing employment, living independently, and relationship experiences with partners as well as family formation.

Readmission drivers for children with medical complexity: Home nursing shortages cause health crises.

OBJECTIVE: Children with medical technology dependence (MTD) are frequently readmitted to the hospital. However, due to their medical fragility, it is often difficult to untangle the root causes for readmissions to identify the most effective preventive approaches. We sought to explore environmental and family factors driving hospital readmissions for children with MTD. DESIGN: Semi-structured, in-person interviews were conducted with state-wide care coordinators for children with MTD in Illinois with at least 1 year of experience. Interview topics related to children with MTD transitioning from hospital-to-home, essential supports for living in the community, and factors which influenced and prevented hospital readmission. The interview guide served as an initial codebook which was iteratively modified as themes emerged. RESULTS: Fifteen care coordinators with on average 6.6 years of experience were interviewed. They described that lack of home nursing was one of the primary drivers of readmissions due to parental exhaustion and lack of medical expertize in the home. Unavoidable medical admissions, a lack of a plan for emergencies, and home environmental factors also contributed to readmissions. CONCLUSION: Hospital readmission is an expected occurrence for children with MTD, yet still may be substantially reduced through consistent, quality home health nursing to bolster family capacity and allow for respite from constant caregiving. Improved incentives for the home health workforce to increase manpower would be ultimately offset by reduced hospitalizations for children with MTD. Additionally, more research is needed to understand which home nursing structures and skills optimally support families in the reality of manpower scarcity.

Unmet Respite Needs of Children With Medical Technology Dependence.

Children with medical technology dependency (MTD) require a medical device to compensate for a vital body function and substantial nursing care. As such, they require constant high-level supervision. Respite care provides caregivers with a temporary break, and is associated with reduced stress; however, there are often barriers. The study utilizes mixed methodology with the National Survey of Children with Special Health Care Needs (NS-CSHCN) and semistructured interviews with state-wide care coordinators to understand the gap for respite care services. Fifty-nine percent of parents who needed respite care received none. Parents of older children with MTD were more likely to report respite needs. Care coordinators described that home health shortages created barriers to respite care utilization, and the lack of respite care can lead to hospital readmission. Although respite care is a vital resource to support families of children with MTD, it is infrequently available, which can have severe consequences.

Attributable Delay of Discharge for Children with Long-Term Mechanical Ventilation.

OBJECTIVE: To assess the reasons for discharge delays for children with long-term mechanical ventilation. STUDY DESIGN: Charts of children (0-18 years of age) with a new tracheostomy in the Pulmonary Habilitation Program at the Ann and Robert H. Lurie Children's Hospital of Chicago were retrospectively reviewed for demographic information, medical diagnoses, medical stability, discharge to home, reasons for discharge delay, and hours of staffed home nursing. All patients were discharged on mechanical ventilation. Discharge delay was defined as >10 days after medical stability. Hospital charges were analyzed and excess charges quantified beginning with the date of delay. Descriptive statistics and Pearson χ2 tests were used to compare nursing hours and demographics. RESULTS: Of 72 patients, 55% were male with mean age 1.8 years (SD 3.8) at tracheostomy placement. The most common long-term mechanical ventilation indication was chronic lung disease (n = 47, 65%); 54% had discharge delays, the majority were primarily due to lack of home nursing (62%), followed by delay of caregiver training (18%), caregiver health and social issues (8%), and delay in a transitional care facility bed (8%). Of the 39 delayed patients, 10% ($13 217 889) of hospital charges occurred during excess days with a median of $186 061 (IQR $117 661-$386 905) per patient. CONCLUSIONS: Over one-half of children discharged to the community from a large inpatient pediatric long-term mechanical ventilation program had a nonmedical delay of discharge home, most commonly because of home nurse staffing. This case series provides further evidence that limited availability of home nursing impedes efficient discharge and prolongs hospitalizations.

Effect of CPAP therapy on kidney function in patients with obstructive sleep apnoea and chronic kidney disease: a protocol for a randomised controlled clinical trial.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in patients with chronic kidney disease (CKD) and may contribute to the progression of kidney disease either through direct effects of hypoxia on the kidney or indirectly through hypoxaemia-induced oxidative stress, endothelial dysfunction, inflammation, activation of the renin-angiotensin and sympathetic nervous systems, and hypertension. Treatment of OSA with continuous positive airway pressure (CPAP) improves many of these physiological abnormalities in patients with normal renal function, though to date there are no trials evaluating the effect of OSA treatment on kidney function in patients with CKD. The purpose of this study is to test the feasibility and efficacy of CPAP therapy in CKD patients with OSA. METHODS AND ANALYSIS: The study is a randomised, controlled, non-blinded, parallel clinical trial in which patients with established CKD are screened for OSA. Patients with OSA are randomised to either conventional medical therapy (control group) or medical therapy and CPAP (CPAP group) and followed for 1 year. The primary outcome is the change in estimated glomerular filtration rate. Secondary outcomes are the change in the urinary albumin/creatinine ratio, the Epworth Sleepiness Scale , Pittsburgh Sleep Quality Index and Kidney Disease Quality of Life questionnaire. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Conjoint Health Research Ethics Board (ID: REB15-0055). Results from this study will be disseminated through presentations at scientific conferences and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT02420184; Pre-results.

Synergistic Modulation of Inflammatory but not Metabolic Effects of High-Fat Feeding by CCR2 and CX3CR1.

OBJECTIVE: The purpose of the study was to explore the impact of dual targeting of C-C motif chemokine receptor-2 (CCR2) and fractalkine receptor (CX3CR1) on the metabolic and inflammatory consequences of obesity induced by a high-fat diet (HFD). METHODS: C57BL/6J wild-type, Cx3cr1-/- , Ccr2-/- , and Cx3cr1-/- Ccr2-/- double-knockout male and female mice were fed a 45% HFD for up to 25 weeks starting at 12 weeks of age. RESULTS: All groups gained weight at a similar rate and developed a similar degree of adiposity, hyperglycemia, glucose intolerance, and impairment of insulin sensitivity in response to HFD. As expected, the circulating monocyte count was decreased in Ccr2-/- and Cx3cr1-/- Ccr2-/- mice but not in Cx3cr1-/- mice. Flow cytometric analysis of perigonadal adipose tissue of male, but not female, mice revealed trends to lower CD11c+MGL1- M1-like macrophages and higher CD11c-MGL1+ M2-like macrophages as a percentage of CD45+F4/80+CD11b+ macrophages in Cx3cr1-/- Ccr2-/- mice versus wild-type mice, suggesting reduced adipose tissue macrophage activation. In contrast, single knockout of Ccr2 or Cx3cr1 did not differ in their adipose macrophage phenotypes. CONCLUSIONS: Although CCR2 and CX3CR1 may synergistically impact inflammatory phenotypes, their joint deficiency did not influence the metabolic effects of a 45% HFD-induced obesity in these model conditions.
